Frequently Asked Questions

Check the machine nameplate and parts manual. GH-series tags list model and series. If it is Series A, 248736 is the correct pump assembly. If your tag shows Series B (or no match), use the series-specific kit for that generation instead.

Persistent loss of pressure, difficulty priming or holding prime, pulsation, material bypass into the wet cup, or visible scoring on pump components typically point to fluid-section wear. If adjustments and packings don’t resolve it, a complete pump assembly replacement is recommended.

Yes—many technicians perform a direct swap following the Graco service manual. Support the sprayer safely, depressurize, isolate fuel/hydraulics as instructed, and follow torque specs and lubrication steps. If you’re unfamiliar with GH-series service, consult an authorized center.

This is a complete fluid section. Depending on wear, you may also service intake/outlet checks, filters, and seals. Replace any damaged gaskets/O-rings and use fresh throat seal liquid after installation and during storage.

The GH-series is used for high-output coatings. Follow your sprayer’s material compatibility chart. Always strain materials and match tip/mesh to the coating to minimize wear on the pump and checks.
